LANTERN.

SPECIFICATION forming part of Letters Patent No. 381,557, dated April24, 1888.

Application filed June 27, ISST.

To all whom, it may concern:

Be it known that I, HARVEY L. J nwELL, a citizen of the United States,residing at Bangor, in the county of Penobscot and State of Maine, haveinvented certain new and useful Improvements in Lanterns; and I dodeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to whichitappertains to make and use the saine.

Myinvention relates to that class oflanterns in which the globe iscarried by aholder, which rises automatically when released, thusaffording easy access to the wick for trimming or lighting, the holdermeanwhile sustaining the globe in the elevated position to which it hasbeen raised.

My invention is more especially directed to increasing the simplicity ofconstruction and cheapness ofthe springs which raise the holder, at thesame time so arranging them that they operate smoothly and directlywithout rubbing or friction. In combination with such arrangement ofsprings, I employ a means of mounting the sliding holder which ispeculiarly well adapted for use with the former.

In order to malte my invention more clearly understood, I have shown inthe accompanying drawings a means for carrying it into effeet.

In said drawings, Figure l is an elevation of a lantern embodying myinvention with the globe and holder down. Fig. 2 is a similar view withsaid parts raised. Fig. 3 is a side view of the upper part of the globeand holder. Fig. 4 is a view of the tilting-plate for holding the lowerpart of the globe detached.

Referring to the drawings, A is the base of the lantern, containing theusual oil-reservoir; E, the burner; B, the air-tubes; C, the centraldrafttubcs. These parts may be of any suitable and preferredconstruction.

D is the cap, provided, preferably, with a sleeve, n, which is fitted toslide vertically on the tube C. Side bars, 7c, are secured to the cap Dand descend to a little below thc level of the burner, where they turninward, their ends forming pivots, upon which is hung upondiametricallyopposite bearings the tilting holder-plate F. The latter isprovided with a Serial Xo. 242511.

circumferential iiange, within which dts neatly the lower edge of theglobe G.

t i.' are wires constituting a spring-clasp adapted to lit the upper endof the globe, the

two wires lying respectively upon the upper V adapted to slidevertically up and down relative to the tubes, base, and burner, thesleeve n moving upon the central tube, C, and the side bars, k,reciprocating in loops or guides ZZ upon the air-tubes B. The liftingand sustainingsprings iorthisslidingframe are shown atm. I may hereremark that but one of these springs is necessary if made of the properstrength; but, for symmetry and convenience, I prefer to employ two, asshown. The springs are secured to the side air-tubes, B, preferably neartheir upper ends, as shown, and extend' inwardly in a substantiallyhorizontal line to the holder-frame,to which they are secured by theirinner ends. I prefer to employ a single piece of wire, which is loopedat its middle around the sleeve n and soldered thereto, if desired, thetwo ends being each bent into one or more coils, in in', to give moreplay and elasticity,and secured by their extremities to the tubes B.Vith such arrangement ofsprings and mounting of the holder-frame uponthe central tube it is very convenient to use the form of catchillustrated.

J is a rod secured to' the sliding frame and projecting above thelantern-frame, as shown. By pressing down upon this rod the holderframebe depressed to its lowerrnostposition against the stress of spring orsprings m. Vhen so depressed, a spring-bar, I, secured to the holdentraine and provided with a shoulder, r, will secure the holder in saidposition by the engagement of said shoulder with a ring or disk, o. Thelatter is secured rigidly to the upper end of thecentraltube,and hasapertures through which the rods J and I pass.

Neither the special form of catch herein shown, involving the parts J,I, r, and 0', nor the special forni of globe-holder involving IOO tube,the lifting-spring m, secured to the main frame, extending inward, andsecured at its inner end to the holder-frame, and at the top of thelatter and near said bearing a catch for I5 holding the sliding frameagainst the stress of said spring, substantially as set forth.
